Description

Technical Field

[0001] This utility model relates to the field of argon arc welding technology, and in particular to an automatic argon arc welding device with an adjustable pressure roller. Background Technology

[0002] Flexible fire-resistant cables are mainly used for power supply in fire protection systems in densely populated and hazardous locations such as schools, hospitals, high-rise and super high-rise residential buildings, shopping malls, theaters, museums, and airport terminals. The 60-type cable metal sheath coating welding and corrugating production line is a key device in the production of copper (aluminum) corrugated sheath flexible fire-resistant cables. The welding quality of the corrugated copper (aluminum) sheath weld directly affects whether the product's air density meets the standard requirements. If the bent cable core pushes against the longitudinal weld seam when entering the welding mold, the weld seam will show incomplete welds or weak welds, affecting the welding quality. Utility Model Content

[0003] The purpose of this invention is to address the shortcomings of existing technologies in the welding of corrugated copper (aluminum) sheaths, which directly affect whether the product's air density index meets the standard requirements. When the bent cable core pushes against the longitudinal weld seam as it enters the welding mold, the weld seam will exhibit incomplete welding or false welding, affecting the welding quality. Therefore, this invention proposes an automatic argon arc welding device with an adjustable pressure roller.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] An automatic argon arc welding device with adjustable pressure rollers includes a base plate. Two symmetrically arranged U-shaped frames are fixedly connected to the top of the base plate. The two U-shaped frames are arranged in parallel. Four symmetrical L-shaped mounting plates are fixedly connected to one side of the top of the base plate. The four L-shaped mounting plates are all located on one side of the two U-shaped frames. The four L-shaped mounting plates are detachably connected to the same adjusting horizontal plate. A welding assembly for welding is provided on the top of the adjusting horizontal plate.

[0006] Both sides of the U-shaped frame are provided with through holes, and a shaping component for shaping the cable core is provided inside the through holes.

[0007] One of the U-shaped frames has a pressing assembly for pressing the cable core fixedly connected to the top side.

[0008] In one possible design, the welding assembly includes a mounting block fixedly connected to one side of the top of the adjusting cross plate, wherein a nylon longitudinal wrapping mold is fixedly inserted through the interior of the mounting block, and two symmetrically arranged protective covers are fixedly connected to the top middle position of the adjusting cross plate.

[0009] In one possible design, the tops of the two L-shaped mounting plates located on the same side are fixedly connected to the same support side plate, an electric push rod is fixedly connected to the top inner wall of the support side plate, the piston rod of the electric push rod is fixedly connected to a sliding plate, one side of the sliding plate is slidably connected to one side of the support side plate, and a welding torch is fixedly installed on one side of the sliding plate.

[0010] In one possible design, four first mounting screws are fixedly connected to both sides of the adjusting plate. Two symmetrically arranged strip holes are opened on one side of the L-shaped mounting plate. One end of each of the first mounting screws passes through the interior of the corresponding strip hole. A first fixing nut is threaded onto the outer wall of the first mounting screw. A washer is also provided between the first fixing nut and the L-shaped mounting plate. The first fixing nut is used to limit the height of the adjusting plate.

[0011] In one possible design, the shaping assembly includes a fixed block fixedly connected to the inner wall of the through hole, a sliding block slidably connected between the inner walls of the two sides of the through hole via a slider and a slide rail, a nylon longitudinal wrapping mold rotatably connected between the two fixed blocks and the two sliding blocks, and a shaping wheel fixedly sleeved on the outer wall of the nylon longitudinal wrapping mold for shaping the cable core.

[0012] In one possible design, two symmetrically arranged limiting screws pass through the top of the U-shaped frame. The bottom of the limiting screws is rotatably connected to the top of the sliding block. A second fixing nut is rotatably connected to the top of the U-shaped frame. The top of the limiting screws is threaded through the second fixing nut, which is used to adjust the height of the limiting screws.

[0013] In one possible design, the pressing assembly includes a hollow box fixedly connected to one side of a U-shaped frame, with an adjusting rod slidingly passing through the bottom of the hollow box. A pressing roller is fixedly connected to the bottom of the adjusting rod, and the bottom of the pressing roller abuts against the cable.

[0014] In one possible design, an upper pressure plate is slidably connected to the inner wall of the hollow box, the top of the adjusting rod extends into the interior of the adjusting rod and is fixedly connected to a lower pressure plate, a compression spring is provided between the upper and lower pressure plates, the two ends of the compression spring abut against the bottom of the upper pressure plate and the top of the lower pressure plate respectively through spring seats, and an adjusting screw is threaded through the top of the hollow box, the bottom of the adjusting screw being rotatably connected to the top of the upper pressure plate.

[0015] In this application, during the production process, copper (aluminum) strip is cut by a cutter and then enters a shaping wheel. It then enters a nylon longitudinal wrapping mold to be longitudinally wrapped into a copper (aluminum) tube, which enters a welding mold. Automatic argon arc welding is performed at the exit of the welding mold. The welded copper (aluminum) tube enters a sizing mold. The welded copper (aluminum) tube enters a cooling water tank for cooling. After cooling, the copper (aluminum) tube enters a traction machine. The welded tube enters a texturing machine for texturing under the traction of the traction machine. After texturing is completed, it is placed on a roll.

[0016] Because the cable core is not perfectly round during cabling, and its surface is not straight, the cable core is irregular. When the cable core passes through the shaping wheel and enters the copper (aluminum) tube longitudinally wrapped by the nylon longitudinal wrapping mold, the bent cable core pushes against the longitudinal wrapping weld seam as it enters the welding mold. At this time, the weld seam will show incomplete welds and weak welds, affecting the welding quality.

[0017] When the cable core enters the copper (aluminum) tube formed by the nylon longitudinal wrapping mold, a pressure roller is used to press the cable core, so that the cable core is close to the copper strip when it enters the copper (aluminum) tube formed by the nylon longitudinal wrapping mold and enters the welding mold. This ensures that the cable core and the weld are kept at a certain distance during welding, thus guaranteeing the quality of the weld.

[0018] Furthermore, the height of the horizontal plate can be adjusted by loosening the first fixing nut to release the braking state of the horizontal plate, thereby adjusting the height of the horizontal plate. After adjusting the height of the horizontal plate, the first fixing nut can be tightened again to adjust the height of the horizontal plate, thereby changing the height of the nylon longitudinal wrapping mold and the mounting block. The welding gun can then perform welding operations. At the same time, the piston rod of the electric push rod can change the height of the welding gun by adjusting the height of the sliding plate, thus improving the applicability of the device.

[0019] By rotating the second fixing nut, the height of the upper fixing block can be changed, which in turn can change the distance between the two shaping wheels, making it suitable for cable cores of different sizes. Moreover, the height of the pressure wheel can be adjusted, and the pressure wheel can always be in contact with the cable by the elastic force of the compression spring. Furthermore, by rotating the adjusting screw, the upper pressure plate can be moved down, thereby adjusting the compression amount of the compression spring and improving the applicability of the device.

[0020] Beneficial effects: When the cable core enters the nylon longitudinal wrapping mold to be longitudinally wrapped into a copper (aluminum) tube, a pressure roller is used to press the cable core, so that the cable core is close to the copper strip when it enters the copper (aluminum) tube longitudinally wrapped into the nylon longitudinal wrapping mold and then enters the welding mold. This allows the cable core to maintain a certain distance from the weld seam during welding, effectively avoiding the problems of missed welds and incomplete welds caused by the cable core bending and pressing against the longitudinal wrapping weld seam when entering the welding mold, thus ensuring the quality of the weld seam.

[0021] Height adjustable: By loosening the first fixing nut to adjust the height of the horizontal plate and then tightening it again, the height of the nylon longitudinal wrapping mold and the mounting block can be changed. In conjunction with the piston rod of the electric push rod, the height of the sliding plate can be adjusted to change the height of the welding gun, so that the device can adapt to welding requirements of different specifications and expand the application range of the device.

[0022] Adjustable spacing: Rotating the second fixing nut can change the height of the upper fixing block, thereby changing the spacing between the two shaping wheels, which can accommodate cable cores of different sizes and improve the versatility of the device.

[0023] The pressure roller can always be in contact with the cable, and the clamping force of the pressure roller can be changed by changing the compression amount of the compression spring, which further enhances the applicability of the device. Attached Figure Description
